yeah, it must be a nullifying technique of some sort. otherwise, itachis giving naruto some of his powers would be pointless. itachi was actually depending on naruto to save sasuke. Itachi was protecting sasuke from the start.

Naruto was given an UNBELIEVABLE power, nothing is as strong as it. If you want to know, look below:

did you miss Naruto use it in Sage mode when he snuck out that night while learning how to become a sage. He did not perfect its use yet but if you remember you saw the big white thing that look like a cloud. That was no cloud! I say no more....

i jsut hope it is something that can help naruto defending not just himself but the whole konoha without him asking the help of the nine tailed beast...it can really be something that can help naruto stop sasuke in destroying konoha for basing on what i've seen in the anime,itachi told naruto that sasuke may not follow the path that he intended for him to follow, and that is protecting konoha just like what he did..

i dont believe he was practicing to do whatever itachi gave him i believe he was practicing his ultimate technique
i think he was given the power to make his mind up on killing suske if he cant be helped

in the best guess of all ages. I'm willing to bet that he gave Naruto the Power to control the 9 tails power to the fullest of there abilities and to resist madara and sasukes ability to control that chakra or whatever.
